Thought I would have a go at deliberately stopping sparging early to get a high quality beer.
I was so excited after my day with Bandit yesterday that I filled the HLT up and got some brewing liquor ready for today
Mashed 7 KG Marris Otter, 0.7 Kg Crystal Malt and 0.3 Kg Wheat Malt with 22 Liters of Liquor at 66 degrees C for 90 minutes, sparged till I had 27 liters and topped up with boiling liquor so I had 50 Liters in the boiler.
I use CRS in the liquor and DLS in the grist
Boiled for just over an hour
Brew length is 36 Liters
30g Fuggles (4%) wort hops (added at sparge time)
50g Northdown (8.4%) 60 minutes
40g Fuggles (4%) and a whirlfloc 15 mins
30g Fuggles after end of boil at 80 degrees C
Reckon this gives about 42 IBU's (anyone care to check this because I'm not confident with hop calculations - ie what utilizations to use)
Cooled to 23 degrees C and pitched 30g S04 which was warming up in some boiled up (and cooled) wort I had in the freezer.
Ended up with 36 Liters at 1.043 SG which is a brewhouse efficiency of 65% at the time of stopping sparging the wort was leaving the mash tun at gravity 1.029
I can't wait to see what it turns out like, thinking about the cost of sacrificing efficiency for better quality beer I would say that 75% of the grain bill would give the same gravity wort with a full sparge and an efficiency of 80% so it has cost 2Kg grain which is about £1.50 or an extra 2 pence per pint!
Started at 8 in the morning and all tidied away by 1pm - 5 hours total, thats a record for me.
Anyway - some pictures
My wort cooling setup - Boiler is just above and the hot wort coming down that white pipe to the CFC

Homemade CFC in action

Temperature monitoring of cooled wort

Running wort from Fermenter into a bucket which is then poured back in to aerate the wort, I like to do it this way because it means I dont have to dip the bucket in the wort and risk dirt.

A well aerated wort, theres 36 Liters under those bubbles


And into the temperature controlled cupboard for a few days, along with some I bottled up yesterday from the last effort.
